LEAK-G LAND FOR PlPES.

SFEGIFICATION forming part of Letters Patent No. 676,944, dated J' une25, 1901.

Application filed October 23, 1900. Serial No. 34,027. (No model.)

To @ZZ whom it may concern:

Be it known that I, HORACE E. FRICK, a citizen of the United States ofAmerica, residing in the city and county of Philadelphia, in the Stateof Pennsylvania, have invented a certain new and useful Improvement inLeal-Glands for Pipes, of which the follow* ing is a trueand exactdescription, reference being had to the accompanying drawings, whichform a part thereof.

Myinvention relates to devices for stopping leaks in pipe-joints, havingfor its object to provide a simple and thoroughly-efiicient device forthis purpose.

The nature of my improvements will be best understood as described inconnection with the drawings in which they are illustrated, and inwhich- Figure l is a side elevation of a pipe-joint with my leak-glandapplied. Fig. 2 is an end view ot' the joint viewed from the side of thepipe-section B. Fig. 3 is a longitudinal section on the line 3 3 of Fig.2. Fig. 4 is a crosssection on the line 4 4 of Fig. 3, and Fig. 5 is aside elevation of one of the movable gland-sections.

A is an internally-threaded pipe-section, A indicating the threadedportion and A2 the end of the pipe-section.

B is an externally-threaded pipe-section screwing into the pipe-sectionA, its threaded portion being indicated at B'. The joint is formedbetween the threaded portions A and B', and my leak-gland is especiallydesigned for stopping leaks in such joint, asis here indicated. l

My device consists ot' a divided clamping ring the sections of which areindicated at C C, said sections being provided with flanges O, whichface each other when the clamp is assembled and are secured together bybolts, as indicated at D D. The clamp-sections O are also provided withperipheral ianges C2, pierced with perforations, as indicated at O3,Fig. l. The body of the clamp is reinforced at intervals, as indicatedat C4, and threaded perforations formed through these reinforcedportions in which screw clamping-screws, (indicated at E E, &c.,) whichsecure the clamping-ring sections to the pipe B and at a distance fromsaid pipe, so as to provide an annular space between the pipe andclampingring.

F F indicate the movable gland-sections of my device, both beingprovided with periph- `gland-sections are secured to the flanges O2 ofthe clamping-ring sections by adjustingscrews, as shown at G G, rbc.

H indicates a. packing-ring or gasket which is placed around the pipe Bso as to rest against the end A'2 of the pipe A and which is pressedagainst the end of the joint by the action of the gland-sections F F.

In practice where a leak occurs the clamping-ring sections and glandsections are placed together, as indicated in Fig. 4E, and then thenested sections placed around the pipe, as also shown in said figure,and the clamping-ring sections secured together by the bolts D D. Thebinding-screws F. are then screwed down against the pipe Bi, so as toclearly fasten the clamping-ring in place thereon, and then the movablegland-sections F F are pressed forward against the gasket H by screwingup bolts G G.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A leak-gland for pipes having in combination a divided clamp `ring CC having means for securing its sections together and binding-screws, asE E, dsc., for securing it to and at a distance from the pipe, a dividedgland F F having slots F4 through which pass the binding-screws E andmeans for drawing the gland-sections into the space between the pipe andclamp-ring.

2. A leak-gland for pipes having in combination a divided clamp-ring O Oprovided with a iiange, as O2, and having means for securing itssections together and bindingscrews, as E E, the., for securing it to.and at a distance from the pipe, a divided gland F F having a flangeF', slots F'L through which pass the binding-screws E andadjustingscrews G G, the., for securing the gland-sections to theclamp-ring.
